01 — Overview
Introduced in 1968, the DT-1 established what Yamaha calls the "trail bike" category at a time when on-road and off-road machines were not clearly distinguished. It was equipped for off-road use, with what was then the longest-stroke front fork on any Japanese model, block-pattern tyres and an engine guard. Engine: air-cooled 246 cm³ two-stroke single.

ENGINE
Single
One cylinder: light, simple and characterful. Found everywhere from commuters to off-road machines and classics. A power stroke every revolution: light, simple and explosive — and, as emissions rules tightened, gradually retired from road machines.General description of the layout
